Abstract: PURPOSE:To uniformly machine a work with a different locus for each rotation and set the center of the sway range at an optional position with respect to a lower surface plate by allowing an upper surface plate to perform a synthesis motion with sways crossing each other and making sway cycles adjustable individually. CONSTITUTION:When a lower surface plate 3 is rotated by a motor, a work is also rotated, and an upper surface plate 4 is rotated by the rotation of the motor. When the motor is further rotated, a T-groove table 14 is rotated, a slide piece at an eccentric position from the rotation center of the table 14 applies a sway motion to a main link arm 10 to sway the upper surface plate 4 in the C direction, concurrently a table 15 is rotated by the rotation of the fourth drive motor, a piece 13 applies a sway motion to a sub-link arm 11 to sway the upper surface plate 4 in the E direction. These sways apply a synthetic motion in the left & right and back & forth directions to the upper surface plate 4, which is slidingly rotated while being brought into contact with the work by the pressure of a spring to perform lap-machining. By fitting an arm 6 slantly with the arm 10, the center of the sway range can be set to an optional position.

Title: Heat-treatment method
Inventor: KOBAYASHI JUNICHI
IPC: C30B31/12
Filed: 1994-05-17
Abstract: PURPOSE:To prevent a slip from being generated when a wafer as an object to be treated is heat-treated by a method wherein the wafer is heat-treated at a temperature- rise pattern whose temperature-rise speed grade is smaller than that of a limit temperature-rise speed pattern which can prevent the generation of the slip of the object, to be treated, at a predetermined treatment temperature. CONSTITUTION:Many semiconductor wafers W are held by a ladder boat 6, the arrangement pitch of the wafers W is set, e.g. at 3/16 inch, and they are carried into a reaction tube 2. Then, the temperature at the inside of the reaction tube 2 is raised at high speed, e.g. at 34 deg.C/min, until a heat-treatment region inside the reaction tube 2 becomes a temperature of about 900 deg.C. Then, after the temperature of the heat-treatment region inside the reaction tube 2 has reached 900 deg.C, the temperature is raised stepwise at low speed, e.g. at about 10 deg.C/min, up to 980 deg.C and, in addition, at about 5 deg.C/min up to 1100 deg.C. The temperature-rise speed is set on the basis of a result by observing the existence of the generation of a slip while various temperature-rise speed patterns are changed at every arrangement pitch of the wafers W. Thereby, it is possible to prevent the slip from being generated while the wafers are being treated at a high throughput.

Title: Method and apparatus for preparing thermally shrinkable tube of large diameter
Inventor: KAIZU RIYOUSUKE
IPC: B29C55/22
Filed: 1982-07-22
Abstract: PURPOSE:To obtain a tube of high and uniform quality and excellent yield by a method wherein a hot plastic tube is heated uniformly and uniform expansion due to gas is controlled mechanically. CONSTITUTION:Gas is supplied through a valve 2 into a guide pipe 1 to expand a tube 5. This expansion continues until the tube 5 touches the internal wall of a nearly octagonal column formed by four movable plates. Then, an upper and a lower movable plate 19, 20 are made a little larger. At this time the tube 5 begins to expand. Subsequently, the distance between a right and a left movable plate 21, 22 is magnified as that between the upper and the lower movable plate is. When the tube 5 expands and sticks sufficiently to the walls of the movable plates 19-22, the distance between the upper and lower movable plates and that between the right and left movable plates are magnified respectively in this order similarly to the former handling. Repetition of such operations magnifies the tube up to the prescribed dimension. When the tube 5 is cooled, it is degassed to remove the guide pipe 1 from the device. The tube 5 fitted to the guide pipe 1 is expanded to make an octagon having curved surfaces at the corners.

The portion 301 is not darkened and permits the emitted light to pass. Since the light-screening plate is made to opaque to its inner portion, with a light-passing window 4 being remained by the simple process of selectively emitting the shorter-wavelength light, the light does not leak out of the portion 301, and the stray light can completely prevented. Furthermore, the accuracy in forming the window is high, and the window with a small area can be formed.

Title: Production of hot-rolled steel plate of superior workability of weld zone
Inventor: TAKITA MICHIO
IPC: B22D11/115
Filed: 1979-10-05
Abstract: PURPOSE: To obtain a hot-rolled steel plate of superior workability of weld zone by performing continuous casting while giving electromagnetic flow to the freezing interface of molten steel which contains predetermined amounts of specific element and has been controlled of oxygen content.  
     CONSTITUTION: This steel has the composition comprising 0.02W0.12% C, ≤0.01% Si, 0.1W0.7% Mn, ≤0.025% P, ≤0.020% S, ≤0.005% Al, and iron and unavoidable impurities for the remainder. This is controlled to 70W250ppm oxygen counted. The composition controlling is accomplished by subjecting the molten steel, which is tapped at a higher carbon content than the target, to vacuum degassing treatment to undergo decarburizing and deoxidizing, whereby the above- mentioned oxygen content is attained. Electromagnetic flow is applied to the freezing interface of this molten steel to suppress the formation of air bubbles. The term "electromagnetic flow" refers to the filmlike molten steel flow effective for the suppression of the pinhole nucleus formation that is applied to the entire circumference of the freezing interface in the mold, and particularly to the electromagnetic flow that is applied by the linear motor installed in the mold or right thereunder. thereby, the hot-rolled steel plate of superior workability of weld zone is obtained.

Abstract: PURPOSE:To transfer a sector which has an error at its subordinate header in real time by adding interleaving length as fixed length to a sector address which is transferred one cycle before if the sector having the error at its subordinate header is found. CONSTITUTION:A CD-ROM controller 34 when finding a sector which is to be transferred to a host computer 30 and an ADPCM decoder 33 and has no error at its subordinate header stores header information as its sector address. Each time a sector having no error is read out thereafter, header information is stored. If the sector having the error at its subordinate header is found, the interleaving length as the fixed length is added to the sector address which is transferred one cycle before. Consequently, when the result matches the current sector address, it is judged that the sector should be transferred and the value of the subordinate header including the error is estimated from repetition timing to correct the error.
